The bifilar pancake coil at its resonant frequency

[synchro1]

Yes...

The scrapyard we visited to view an early Tesla Electro-magnet in 62' was guarded by an old guy who told us the magnet fired accidently once while it was on it's side, and knocked a junk car off the top of a pile into a neighbor's yard at a distance of maybe fifty yards. We were not permitted to photograph it.

If evostars aimed his pancake coil at at cutlery rack, instead of measuring voltage, he'd be as traumatized as I was when I first tried it. The NC EMP Sats are atomic warheads in the Ionosphere that are designed to implode a Magnetic Tsunami from the Earth's magnetic field.

Oh-so now we have electromagnets that repel steel cars


Where or how do you keep coming up with this stuff synchro lol.

Well, MileHigh,  can a square wave be considered pulsing a bifilar coil?

Conrad nicely demonstrates in his videos, especially in Part 1 https://www.youtube.com/watch?v=fC84W0PIZoE
when he switches from pure sine wave to square wave at 4 MHz, the bifilar coil nicely responds to
that wave much the same way as it does for the sine wave and of course the output response is sine wave as expected.
It gives pretty good response even to subharmonic (1/3) square wave excitation as well.

Is this still a strange question?

Yes it's a strange question because it was a discussion about Magluvin's mistaken belief that "since a series bifilar coil can look like the wire resistance only, then I can pulse a series bifilar coil and get an instant magnetic field without having to energize the inductor."  It wasn't about the bandwidth-limited square wave excitation that you see in Conrad's clip.

@Tinman,

My vendetta with TK goes back to one of his earliest coil comparison videos nearly eight years ago. I had a large coffee can size solenoid bifilar professionally wound at an electric motor shop in Eureka California around the same time, and packed the core with welding rods for my first Bedini SSG. I already knew how to charge and pulse the coil from Dave Dinan, but I really didn't know exactly what to expect. I shocked twice; Once to shock charge and ring  it, then a second time. The spark from the second swipe was around ten times as large as the ring pulse. Well, everyone's already heard about the rack of carving knives that careened about twenty five feet towards the coil. The coil was unaffected by the attraction.
